* Prevent URL itype from being lowercased by default

All indicator types except URLs will now be lowercased by default. A user must explicitly pass lowercase=True to the Indicator() init on a url to get it to actually lowercase it. This is to prevent URLs with case-sensitive paths from not being stored/reflected properly.

* eliminate spaces

* rogue whitespace annhilation
